SELECT my GUID into a variable using SQL Stored Procedures?

I have a stored procedure in SQL Server 2008 that I want to store a GUID that I Select into a local variable for further use. I am trying it as below (and with several other variations), but am getting a syntax error near '@myvars'...

DECLARE @myvars uniqueidentifier;
SELECT ID 
INTO @myvars
FROM Device
WHERE DeviceID=@DeviceID

Any help is appreciated. Than开发者_运维百科ks!

try:

DECLARE @myvars uniqueidentifier --declare the local variable to store value in

SELECT @myvars=ID                --assign's the ID column into the variable
FROM Device
WHERE DeviceID=@DeviceID

quick test:

DECLARE @myvars uniqueidentifier --declare the local variable to store value in
declare @x table (id uniqueidentifier, valueOf varchar(4))

insert @x values (NEWID (),'aa')
insert @x values (NEWID (),'bb')
insert @x values (NEWID (),'cc')

SELECT @myvars=ID                --assign's the ID column into the variable
FROM @x
WHERE valueOf='bb'

SELECT @myvars
select * from @x

OUTPUT:
